Another way to make a flat bottom geodesic dome

- This is a very simple method to make a flat base on any frequency geodesic dome. Any frequency, works with class I and class II geodesic domes. This also makes for better door openings, and fitting against a wall.

really loved this video and your right no one else that I know of has looked at these domes on the vertical axis.great work!
Great video, Paul. A lot of really well explained design considerations for anybody making their own dome.
Wow, great information. I thought all even frequency domes would be flat, but I guess not. Never considered looking at them from a vertical axis. Thanks for posting.
If you use the standard strut lengths for even frequency domes you do. In this video he modified the 4v dome to have 4 strut lengths instead of the usual 6.
Beautiful!
thank you
Interesting concept... I would be interested in knowing how this effects the "tension rings" that circle about the widest parts of the dome and hold the outward force developed from the gravitational load from the weight of the structure. There are two such rings that circle a 3 frequency dome. Drawn through the virtices
Hello Paul thanks for this helpful video I'm using one of your plans to make a dome (GD 15) I want to make a 4/9 instead of a 5/9 dome to make it less high as I am raising the dome onto a 150 cm wall. I guess this alteration will influence the diameter of the base. is there any way of calculating the actual diameter of the base of a 3/8 3V. I believe the calculators online only give you the diameter of the sphere ?
The base will be the same size because if you joined a 5/9th to a 4/9th you get a sphere so the join must be the same. Just be careful with the base because one is the inverse of the other. 12 degrees on the top but when one slip up the other slopes down.
great, Paul please tell me what 3D software you using?
it called SketchUp. The basic program is free to download. There is a Pro version too. Not sure if that is the version Paul is using.
I thought any positive frequency dome would have a flat base, is that not true ?
But did you say the ‘ con ‘ is more strut lengths ?
Any even frequency, 2, 4, 6 etc when divided in half will have a flat base (as a rule but not true all the time) All frequency domes can have a flat base but only if divided vertically down the centre.
Hi Sir, I wanna order 3v 6m diameter geodome from you. Please help out@
which graphic editor?
Paintshop pro for windows 98 I run a virtual pc on y mac to run it. I started with it and not had time to learn a new program.
eeeeeeeeh
